The inrush current was way too high. It must have been something over 70A I believe. It had to be at least so high that the connector or the plasic weldeld together Where you using cheap xt90 connector’s? Otherwise, I got no explanation
Could have sworn i read a post that someone thought they got fake xt90 Connectors.
Well it is a 12s8p. I’m going to have to test my next loop key first on one if my smaller batteries not inside if the board.
Where did you get the xt90 connector?
The antispark one or the regular connector. The antispark I had laying around I think I originally got them on Amazon but the others in the batch have worked.
The antispark is an xt60 or xt90?
I have some cheap regular tx90 connectors mixed with good ones I may have used those if it makes a difference.
Put this on the wrong thread. I see the green “L” but perhaps its not really a XT90s. there’s loads of fake ones out that don’t actually work
In my opinion, the only possibility is that somehow the current got way too high and melted the plastic or welded the connector together.
I’ve also seen where it isn’t pushed in ALL the way and makes little arc current sparks.
It sparked before I pushed it all the way in I’m going to assume then antispark is faulty.
That is some weird ass shit.
What a mess. Glad it didn’t get any worse.
I don’t see an S on that male connector. Maybe you grabbed a plain xt90 male? Not sure if it has any effect but hey I did notice. Ones I got from Amazon.
I did use a plane tx90 male I didn’t think there was a difference.
I’m not sure if it matters. If you have an S one laying around I’d try that just to be extra safe.
U can also double click the drag handle and it’ll auto find end of range and fill. Cntl+D good too
@Battosaii the male doesn’t matter but the female has to be an “S” variant.
Would you photograph your setup and how the battery is/was connected to everything else?
Are you sure you weren’t shorting the battery out?
I had this problem once and ended up destroying my VESC
Doubled checked everything and there was no reverse polarity or wires exposed was just random.
Maybe a faulty or fake XT 90 S?
